Filtreau Moving Bed Filter – 190L Bio Chamber (For Ponds up to 30,000L)

High‑capacity biological filtration for koi and ornamental ponds

The Filtreau Moving Bed Filter (190L) is a standalone biological filtration chamber designed to deliver crystal‑clear, stable water quality in ponds up to 30,000 litres. Its 190‑litre chamber holds approximately 100 litres of moving bed media, providing exceptional nitrification performance for koi systems with medium to heavy feeding.

This unit is typically installed after a drum filter or sieve, ensuring that mechanical waste is removed before biological treatment.

Product Overview

The Filtreau 190L Moving Bed Filter uses constant aeration to keep floating media in motion, maximising oxygen transfer and bacterial colonisation. This “boiling” action ensures efficient conversion of ammonia and nitrite into nitrate, supporting a healthy pond ecosystem.

Built from durable PE housing, the unit is weather‑resistant and suitable for long‑term outdoor installation.
